- Release Pressure: Once cooking is complete, allow the Instant Pot to release pressure naturally for 5 minutes, then carefully use the quick-release method to release the remaining pressure. Unlock and remove the lid.

- Freezing: This dish freezes well! Store the cooled pasta in a freezer-safe container for up to 3 months. To reheat, thaw in the fridge overnight and reheat on the stovetop or in the microwave.
- Separate the Cheese: If you plan to store leftovers, it’s best to store the cheese separately and add it when reheating to maintain its creaminess.
Pro Tips
- Don’t Overcrowd the Pot: If you need to, cook in batches to avoid overcrowding and ensure everything cooks evenly.
- Adjust the Seasoning: Taste the sauce before pressure cooking and adjust the seasoning to your liking. You may want to add a pinch of salt or more Italian seasoning depending on your preferences.
- Check the Pasta: After cooking, check the texture of the pasta. If it’s too firm, simply add a little more water and cook on the stovetop for a few more minutes.
- Use Pre-cooked Sausage: For an even quicker version, you can use pre-cooked Italian sausage to reduce the cooking time.
